Another gift from Tory rail privatisation: graffiti at Kensal Green station. All right, the Tories didn' actually put the graffiti there but the way they privatised the railways made it a lot harder to get off.
The reason is that the train operator only leases the platforms and the ticket office area. The rails and the land beneath the platform, the tunnels and the area of the roof and above (where you can see the graffiti vandals have been busy) are still the responsibility of Network Rail.
This roof area has been cleaned before and it has been cleaned since this photo was taken, but it does feel like a Labour of Sisyphus.
